What is the circumference of a circle with a diameter of 12? (Use π ≈ 3.14)

To find the circumference of a circle, you can use the formula:

Circumference = π × diameter.

In this case, you are given a diameter of 12. Using the approximation of π as 3.14, you can calculate the circumference as follows:

Circumference = 3.14 × 12.

Carrying out the multiplication:

3.14 × 12 = 37.68.

This means the circumference of the circle is approximately 37.68.

Therefore, the correct answer aligns with the calculations leading to 37.68, making it clear why this is the accepted answer. The other options do not match the result obtained from the formula, thus confirming that 37.68 is the accurate circumference of the circle.
